[0050] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0051] like Figure 1 FIG. 1 is a flowchart of a method for quickly charging a battery vehicle based on historical data provided by an embodiment of the present invention, the method comprising:

[0052] S100, constructing a device detection local area network, wherein the device detection local area network includes a plurality of wireless communication modules and sockets, wherein a detection device is provided in the socket, and the detection device is used to determine whether a plug is currently inserted in the socket.

[0053] In this step, a device detection local area network is constructed. A charging pile includes multiple sockets, each of which can be charged. The sockets are equipped with a built-in detection device, which may be a distance sensor or a micro switch, etc., for determining whether the plug is inserted into the socket. The charging pile is provided with a charging control panel, and the charging control panel is provided with a QR code or an NFC module for manual charging. A wireless communication module is provided in the charging control panel, and the wireless communication module may be Bluetooth communication or WIFI communication, and is used for data interaction with the electric vehicle. The current electric vehicle is gradually becoming more intelligent, and the electric vehicle has a Bluetooth module or other wireless communication functions.

[0054] S200, establishing a data connection with a data communication module in the battery vehicle, and obtaining historical charging data sent by the data communication module.

[0055] In this step, a data connection is established with the data communication module in the battery vehicle. In order to determine the position of the battery vehicle, when the charger plug of the battery vehicle is inserted into the socket, it will be detected by the detection device. When it is determined that there is a plug inserted in the corresponding socket, the wireless signal detection is performed through the wireless communication module. In this process, the current position of the battery vehicle is located by detecting the local area network through the device, and the position of the data communication module on the battery vehicle is used as the position of the battery vehicle. After determining the position of the battery vehicle, the battery vehicle sends historical charging data to the outside through the data communication module. That is, during the charging process, the battery vehicle will store the data of the last charging process, that is, the historical charging data, which is used for identity identification and verification, and the wireless communication module on the charging pile is used to receive the historical charging data.

[0056] S300, extracting features from historical charging data to obtain charging feature data, and performing online query based on the charging feature data to determine the identity information of the current electric battery vehicle.

[0057] In this step, feature extraction is performed on the historical charging data. When the electric vehicle is charging, the charging pile also records the charging data of the electric vehicle. When recording, the data is recorded by extracting features, and the extracted features are stored in the cloud server. When the historical charging data is received, feature extraction is also performed on the historical charging data to obtain charging feature data, which is matched with the features in the cloud server. The identity of the current electric vehicle is determined based on the matching relationship between the features. Each electric vehicle is bound to a corresponding mobile device.

[0058] S400, query the mobile device bound to the current battery vehicle, send a charging request to the mobile device, and after obtaining user authorization, control the corresponding socket to supply power. During the power supply process, continue to authenticate the identity.

[0059] In this step, the mobile device bound to the current electric vehicle is queried. One electric vehicle is allowed to be bound to one mobile device. Therefore, when charging, a charging request is sent to the mobile device through the cloud server. At this time, the user is informed of the current charging vehicle, vehicle information, charging pile location, charging pile number and fee information through the mobile device. After the user confirms, the authorization can be directly performed through the mobile device. In this process, the bill payment processing is automatically completed. If the user gives pre-authorization, the mobile device is allowed to directly authorize the charging pile to achieve the purpose of automatic charging, eliminating the steps of scanning the code and paying for the user. In addition, in the present invention, in order to avoid the phenomenon of unauthorized charging during the power supply process, real-time identity authentication is performed on the electric vehicle being charged during the charging process. When the verification fails, the power supply is stopped.

[0060] like Figure 2As shown, as a preferred embodiment of the present invention, the step of establishing a data connection with the data communication module in the battery vehicle and obtaining the historical charging data sent by the data communication module specifically includes:

[0061] S201, query the status of the detection device, determine the corresponding socket position when the plug is detected to be inserted, and perform wireless signal detection through the wireless communication module.

[0062] In this step, the status of the detection device is queried. When the plug of the battery vehicle charger is inserted into the socket, the detection device will detect it. At this time, the charging pile determines the socket currently plugged in. At this time, it is determined that there is an electric vehicle that needs to be charged. The wireless communication module in the charging pile is started and begins to detect nearby wireless signals, such as WiFi signals or Bluetooth signals.

[0063] S202, positioning the battery vehicle based on the device detection local area network, determining the corresponding wireless signal of the battery vehicle, and broadcasting the communication address of the current battery vehicle to the outside.

[0064] In this step, the battery vehicle is positioned based on the device detection local area network. Specifically, a charging pile is equipped with at least two groups of wireless communication modules. Each wireless signal is detected simultaneously by the wireless communication module, and the distance value between the source of the wireless signal and each wireless communication module is calculated based on the strength value of the wireless signal, and the position of the battery vehicle is determined according to the relative position relationship between the wireless communication modules and the distance value. Specifically, a three-dimensional coordinate system is constructed, and each wireless communication module is marked in the three-dimensional coordinate system. The distance value R between each wireless communication module and the battery is determined, and a spherical area is constructed with the wireless communication module as the center and the distance value as the radius. The center of the overlapping part of the spherical area is regarded as the position of the battery vehicle. The position of the battery vehicle is determined according to the position of the corresponding socket, and the communication address of the current battery vehicle is broadcasted to the outside. When the built-in data communication module of the battery vehicle detects its own communication address, it determines that the positioning is successful and starts data transmission.

[0065] S203, receiving and storing the historical charging data broadcasted from the data communication module corresponding to the battery vehicle.

[0066] In this step, historical charging data broadcasted from the data communication module corresponding to the battery vehicle is received. When the battery vehicle is charging, the real-time charging indicators are recorded, such as the real-time charging power, thereby obtaining multiple information recording coordinates. For example, at time A, the charging power is a. Then, when the battery vehicle is transmitting data, it broadcasts the historical charging data. At this time, the above data is recorded through the wireless communication module in the charging pile. At this point, the wireless communication module obtains complete historical charging data and temporarily stores the above historical charging data.

[0067] like Figure 3 As shown, as a preferred embodiment of the present invention, the steps of extracting features from historical charging data to obtain charging feature data, performing online query based on the charging feature data, and determining the identity information of the current battery vehicle specifically include:

[0068] S301, retrieve historical charging data, mark it in a two-dimensional coordinate system, and connect it with a smooth curve to obtain a historical charging curve.

[0069] In this step, historical charging data is retrieved and a two-dimensional coordinate system is constructed. Since the historical charging data consists of multiple information recording coordinates, they are marked in the two-dimensional coordinate system. The above information recording coordinates will become discrete points in the two-dimensional coordinate system and are connected by smooth curves to obtain the historical charging curve.

[0070] S302, sampling data of the historical charging curve according to a preset sampling interval to obtain a plurality of sampling coordinates, and generating a sampling character string by comparing adjacent sampling coordinates.

[0071] In this step, data sampling is performed on the historical charging curve according to a preset sampling interval. For example, the sampling interval is 20ms. A plurality of sampling coordinates are collected from the historical charging curve according to the sampling interval. The horizontal coordinate of the sampling coordinate is the time value, and the vertical coordinate is the charging power. The vertical coordinates of two adjacent groups of sampling coordinates are compared, that is, the sampling coordinates (n, M1) and (n+1, M2) are compared. If M2 is greater than M1, the sampling character is 1, indicating that the charging power here increases. If M2 is not greater than M1, the sampling character is 0, indicating that the charging power here does not increase. Each sampling coordinate will correspond to a sampling character. The sampling characters are spliced ​​to obtain a sampling character string.

[0072] S303, converting the format of the sampled character string to obtain charging characteristic data, querying a database preset in the cloud server according to the charging characteristic data, and determining the identity information of the electric battery vehicle, wherein the identity information of the electric battery vehicle is determined by a unique identification code.

[0073] In this step, the format of the sampled character string is converted, such as converting it into decimal or hexadecimal. After the conversion, the charging characteristic data is obtained. During the charging process of the electric vehicle, the charging pile imports the charging data of this time into the cloud server, and the sampled character string is extracted in the same way, and the charging characteristic data is further extracted. By comparing the real-time charging characteristic data with the charging characteristic data in the cloud server, the overlap rate between the two is calculated. When the overlap rate reaches a preset value, it is determined that a match has been found, and the identity of the current electric vehicle is determined according to the records in the cloud server, and a unique identification code is extracted.

[0074] like Figure 4 As shown, as a preferred embodiment of the present invention, the query of the mobile device bound to the current battery vehicle, sending a charging request to the mobile device, and controlling the corresponding socket to supply power after obtaining user authorization, and continuously performing identity authentication during the power supply process, specifically includes:

[0075] S401, sending a charging request to a mobile device according to the identity information of the battery vehicle, wherein the charging request includes location information, number information and fee information of the charging pile.

[0076] In this step, a charging request is sent to the mobile device based on the identity information of the electric vehicle. Since one electric vehicle is bound to one mobile device, the mobile device can be queried through the cloud server and the corresponding charging request is sent to it to seek authorization from the mobile device. Of course, the user can perform pre-authorization, that is, when receiving the charging request, directly agree, send an authorization instruction, and inform the user.

[0077] S402, receiving an authorization instruction sent from a mobile device, supplying power to a corresponding socket, and starting billing.

[0078] In this step, an authorization instruction is received from a mobile device. When the charging pile receives the authorization instruction, it starts to supply power to the corresponding socket. At this time, the electric vehicle starts to charge. During this process, the charging pile records the charging data of this time. Similarly, the electric vehicle also records the charging data at this time.

[0079] S403, during the power supply process, receiving the verification data sent from the data communication module in real time, verifying the identity of the battery vehicle in real time based on the verification data, and interrupting the power supply when the identity verification fails.

[0080] In this step, during the power supply process, the verification data sent from the data communication module is received in real time, the data communication module obtains the real-time charging data, and the real-time charging data is stored in the form of coordinates. The content is the same as the information recording coordinates, the time value is the horizontal coordinate, and the real-time charging power is the vertical coordinate. The sizes of the two adjacent groups of real-time charging powers V1 and V2 are compared. If V2 is greater than V1, a real-time charging feature is generated with a value of 1. If V2 is not greater than V1, a real-time charging feature is generated with a value of 0. The real-time charging feature is disseminated outwardly through wireless broadcasting. The wireless communication module on the charging pile verifies according to the real-time charging feature and the charging data corresponding to the charging pile. If they match, it is determined that the verification is passed. If the verification fails for multiple consecutive times, the power supply is stopped.

[0081] like Figure 5 As shown, a battery vehicle fast charging system based on historical data is provided in an embodiment of the present invention, and the system includes:

[0082] The local area network construction module 100 is used to construct a device detection local area network, which includes multiple wireless communication modules and sockets. The sockets are provided with detection devices for determining whether a plug is currently inserted into the socket.

[0083] In this system, the local area network construction module 100 constructs a device detection local area network. A charging pile includes multiple sockets, each of which can be charged.

The charging pile is provided with a charging control panel, and the charging control panel is provided with a QR code or an NFC module for manual charging. A wireless communication module is provided in the charging control panel, and the wireless communication module can be Bluetooth communication or WIFI communication, which is used to interact with the data of the battery vehicle. The current battery vehicles are gradually becoming more intelligent, and the battery vehicles have Bluetooth modules or other wireless communication functions.

[0084] The data communication module 200 is used to establish a data connection with the data communication module in the battery vehicle and to obtain historical charging data sent by the data communication module.

[0085] In this system, the data communication module 200 establishes a data connection with the data communication module in the battery vehicle. In order to determine the position of the battery vehicle, when the charger plug of the battery vehicle is inserted into the socket, it will be detected by the detection device. When it is determined that there is a plug inserted in the corresponding socket, the wireless signal detection is performed through the wireless communication module. In this process, the current position of the battery vehicle is located by detecting the local area network through the device, and the position of the data communication module on the battery vehicle is used as the position of the battery vehicle. After determining the position of the battery vehicle, the battery vehicle sends historical charging data to the outside through the data communication module. That is, during the charging process, the battery vehicle will store the data of the last charging process, that is, the historical charging data, which is used for identity recognition and verification, and the wireless communication module on the charging pile is used to receive the historical charging data.

[0086] The identity recognition module 300 is used to extract features from historical charging data to obtain charging feature data, perform online query based on the charging feature data, and determine the identity information of the current battery vehicle.

[0087] In this system, the identity recognition module 300 extracts features from the historical charging data. When the electric vehicle is charging, the charging pile also records the charging data of the electric vehicle. When recording, the data is recorded by extracting features, and the extracted features are stored in the cloud server. When the historical charging data is received, similarly, feature extraction is performed on the historical charging data to obtain charging feature data, which is matched with the features in the cloud server. The identity of the current electric vehicle is determined based on the matching relationship between the features. Each electric vehicle is bound to a corresponding mobile device.

[0088] The charging management module 400 is used to query the mobile device bound to the current battery vehicle, send a charging request to the mobile device, and after obtaining user authorization, control the corresponding socket to supply power, and continuously perform identity authentication during the power supply process.

[0089] In this system, the charging management module 400 queries the mobile device currently bound to the electric vehicle. One electric vehicle is allowed to be bound to one mobile device. Therefore, when charging, a charging request is sent to the mobile device through the cloud server. At this time, the user is informed of the vehicle currently being charged, vehicle information, charging pile location, charging pile number and fee information through the mobile device. After the user confirms, the authorization can be directly performed through the mobile device. In this process, the bill payment processing process is automatically completed. If the user gives pre-authorization, the mobile device is allowed to directly authorize the charging pile to achieve the purpose of automatic charging, eliminating the steps of scanning the code and paying for the user. In addition, in the present invention, during the power supply process, in order to avoid the phenomenon of unauthorized charging, real-time identity authentication is performed on the electric vehicle being charged during the charging process. When the verification fails, the power supply is stopped.

[0090] like Figure 6 As shown, as a preferred embodiment of the present invention, the data communication module 200 includes:

[0091] The signal detection unit 201 is used to query the status of the detection device, determine the corresponding socket position when detecting that the plug is inserted, and perform wireless signal detection through the wireless communication module.

[0092] In this module, the signal detection unit 201 performs a status query on the detection device. When the plug of the battery vehicle charger is inserted into the socket, the detection device will detect it. At this time, the charging pile determines the socket currently plugged in. At this time, it is determined that there is an electric vehicle that needs to be charged. The wireless communication module in the charging pile is started and starts to detect nearby wireless signals, such as WiFi signals or Bluetooth signals.

[0093] The vehicle positioning unit 202 is used to locate the battery vehicle based on the device detection local area network, determine the corresponding wireless signal of the battery vehicle, and broadcast the communication address of the current battery vehicle to the outside.

[0094] In this module, the vehicle positioning unit 202 locates the battery vehicle based on the device detection local area network. Specifically, a charging pile is equipped with at least two groups of wireless communication modules. Each wireless signal is detected simultaneously by the wireless communication module, and the distance value between the source of the wireless signal and each wireless communication module is calculated based on the strength value of the wireless signal, and the position of the battery vehicle is determined according to the relative position relationship between the wireless communication modules and the distance value. Specifically, a three-dimensional coordinate system is constructed, and each wireless communication module is marked in the three-dimensional coordinate system. The distance value R between each wireless communication module and the battery is determined, and a spherical area is constructed with the wireless communication module as the center and the distance value as the radius. The center of the overlapping part of the spherical area is regarded as the position of the battery vehicle. The position of the battery vehicle is determined according to the position of the corresponding socket, and the communication address of the current battery vehicle is broadcasted to the outside. When the built-in data communication module of the battery vehicle detects its own communication address, it determines that the positioning is successful and starts data transmission.

[0095] The data broadcast unit 203 is used to receive and store the historical charging data broadcasted from the data communication module corresponding to the battery vehicle.

[0096] In this module, the data broadcast unit 203 receives the historical charging data broadcasted from the data communication module corresponding to the battery vehicle. When the battery vehicle is charging, it records the real-time charging indicators, such as the real-time charging power, thereby obtaining multiple information recording coordinates. For example, at time A, the charging power is a. Then, when the battery vehicle is transmitting data, it broadcasts the historical charging data. At this time, the above data is recorded through the wireless communication module in the charging pile. At this point, the wireless communication module obtains the complete historical charging data and temporarily stores the above historical charging data.

[0097] like Figure 7 As shown, as a preferred embodiment of the present invention, the identity recognition module 300 includes:

[0098] The curve construction unit 301 is used to retrieve historical charging data, mark it in a two-dimensional coordinate system, and connect it with a smooth curve to obtain a historical charging curve.

[0099] In this module, the curve construction unit 301 retrieves the historical charging data and constructs a two-dimensional coordinate system. Since the historical charging data is composed of multiple information recording coordinates, they are marked in the two-dimensional coordinate system. The above information recording coordinates will become discrete points in the two-dimensional coordinate system and are connected by a smooth curve to obtain the historical charging curve.

[0100] The curve sampling unit 302 is used to perform data sampling on the historical charging curve according to a preset sampling interval to obtain a plurality of sampling coordinates, and to generate a sampling character string by comparing adjacent sampling coordinates.

[0101] In this module, the curve sampling unit 302 samples data from the historical charging curve according to a preset sampling interval. For example, the sampling interval is 20ms. A plurality of sampling coordinates are collected from the historical charging curve according to the sampling interval. The horizontal coordinate of the sampling coordinate is the time value, and the vertical coordinate is the charging power. The vertical coordinates of two adjacent groups of sampling coordinates are compared, that is, the sampling coordinates (n, M1) and (n+1, M2) are compared. If M2 is greater than M1, the sampling character is 1, indicating that the charging power here increases.

When the overlap rate reaches a preset value, it is determined that a match has been found, and the identity of the current electric vehicle is determined according to the records in the cloud server, and a unique identification code is extracted.

[0104] like Figure 8 As shown, as a preferred embodiment of the present invention, the charging management module 400 includes:

[0105] The data request unit 401 is used to send a charging request to the mobile device according to the identity information of the battery vehicle, wherein the charging request includes the location information, number information and fee information of the charging pile.

[0106] In this module, the data request unit 401 sends a charging request to the mobile device based on the identity information of the electric vehicle. Since one electric vehicle is bound to one mobile device, the mobile device can be queried through the cloud server and the corresponding charging request can be sent to it to seek authorization from the mobile device. Of course, the user can perform pre-authorization, that is, when receiving the charging request, directly agree, send an authorization instruction, and inform the user.

[0107] The power supply control unit 402 is used to receive the authorization instruction sent from the mobile device, supply power to the corresponding socket, and start billing.

[0108] In this module, the power supply control unit 402 receives the authorization instruction sent from the mobile device. When the charging pile receives the authorization instruction, it starts to supply power to the corresponding socket. At this time, the electric vehicle starts to charge. During this process, the charging pile records the charging data of this time. Similarly, the electric vehicle also records the charging data at this time.

[0109] The real-time verification unit 403 is used to receive the verification data sent from the data communication module in real time during the power supply process, and to verify the identity of the battery vehicle in real time based on the verification data. When the identity verification fails, the power supply is interrupted.

[0110] In this module, the real-time verification unit 403 receives the verification data sent from the data communication module in real time during the power supply process. The data communication module obtains the real-time charging data. The real-time charging data is stored in the form of coordinates, and its content is the same as the information recording coordinates. The time value is the horizontal coordinate, and the real-time charging power is the vertical coordinate. The sizes of two adjacent groups of real-time charging powers V1 and V2 are compared. If V2 is greater than V1, a real-time charging feature is generated with a value of 1. If V2 is not greater than V1, a real-time charging feature is generated with a value of 0. The real-time charging feature is disseminated outwardly through wireless broadcasting. The wireless communication module on the charging pile verifies according to the real-time charging feature and the charging data corresponding to the charging pile. If they match, it is determined that the verification is passed. If the verification fails for multiple consecutive times, the power supply is stopped.

[0111] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
